Given numbers are 897,355,207,507
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,355,207,507 is 12418965.
Find LCM of 897,355,207,507 with Prime Factorization
| 3 | 897, 355, 207, 507 |
| 13 | 299, 355, 69, 169 |
| 23 | 23, 355, 69, 13 |
| 1, 355, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 23 x 1 x 355 x 3 x 13 = 12418965
Therefore, the lowest common multiple of 897,355,207,507 is 12418965.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
897 x 355 x 207 x 507 = 33419434815
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
897 : 1, 3, 13, 23, 39, 69, 299, 897
355 : 1, 5, 71, 355
207 : 1, 3, 9, 23, 69, 207
507 : 1, 3, 13, 39, 169, 507
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,355,207,507, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
355:5x 71
207:3x 3x 23
507:3x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 23 = 2691
Therefore, the value for common factors is 2691.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 33419434815/(1x2691)
LCM = 33419434815/2691
LCM = 12418965
Thus, we can understand that the LCM of 897,355,207,507 is 12418965.
